FRAME FOR MOTOR-VEHICLES.

Application filed July Be it known that I, Li'zorr Laznnons', a citizenof the Republic of France, residing at Issy-lesh Ioulineaux, France,have invented certain new and useful Improvements in Sills for Motor-CarFrames and the Like, of which the following is a specification.

This-invention relates to the construction of the frames of motor-carsand similar vehicles, and more particularly to the construction of thesills constituting such frame.

Among the objects of the invention is to provide a sill of maximumstrength, lightness,

simplicity of construction, and resistance against torsional strain.

Other objects of the invention will appear as the nature of the sameisbetter understood.

The invention resides in certain novel features and combinations ofparts to be hereinafter described, and recited in the claim.

-'In the accompanying drawings, in which similar parts are designated bycorrespondv ing reference characters throughout the several views,Figure 1 is a perspective view of a portion of a sill constructed inaccordance with the invention. Fig. 2 is a vertical transverse sectionof the sill shown in F1g. 1, and Fig. 3 is a similar section of amodified construction. Y.

Referring to the drawings, it will be seen that. the sill forming thesubject-matter of the invention is constituted by two main parts whichhave the form of bars a b, L

The flanges a b of these bars, which are bent up at right angles to thewebs of the same at-eithers1de,-areof unequal width, those of thebar I)being substantially shorter than'those of the bar a.-

The member I) is seated in the open portion of the member L, as shown inFig. 2, so that the flanges of said'bars'abut agalnst and ex tendparallel to each other,a space 0 being left between the web portions ofsaid bars, as shown. The flanges a b of the members a Z) are connectedthroughout their len ths by means of rivets d, which unite said ars inwhat is practically. a unitary structure.

Both the longitudinal and the transverse sills of the frame areconstruct ed in the manner described. .The lrame IH, built up from thesesills in any approved manner, this structure forming no part of thepresent ininvention.

, Instead of having the flanges arranged at a uniform distance apartthroughout the webs of thesills can be made wider, for instance, in thepart at than in the part y for the purpose of increasing the strength atcertainpoints. r

In certain cases for increasing the resistance the outside bar or membera can be arranged as shown in Fig. 3, its lower flange being ofsullicient widtlr to be folded over the lower flange of the inner memberI). In the same way the lowerflange of the inner bar or member could bemade sufficiently wide to be folded under the lower flange of the outer'bar, as will be obvious, or the arrangement shown in Fig. 2 could beretained and a Strengthening-band applied at the point indicated. theresistance of the sill against the strainof the superimposed load, thespace 0 can be filled with any materialsnitable for the purposesuch, forinstance, wood, as shown Having thus described my invention, I claim asnew and desire to secure by Letters Patent- A sillfor motor-car frames,comprising in-.

terconn'ected bars of U-shaped cross-section one of which is seatedwithin the other, one of the side flanges of one of said bars beinglapped about the corresponding flange of the other bar and rivetedthereto.

In testimony whereof I havesigned this specification in the presence oftwo subscrib ing witnesses.
